Before leaving Ikea I head to the kios counter and I join member from there. There is a temporary card out from the machine after registration. It is fast and easy to use the kiosk you need to fill in the form online and cell phone number they will SMS you a code.
To be part of the Family from the date of registration need to spend $200 in a year. I can't wait for the next visit to use the card. Talk of the card, are you one of Ikea family?
